POST AND CLAMP ASSEMBLY BACKGROUND OF THE INVENTION When not worn, wigsare generally mounted on a wig form and stored in awig case. When it isdesired to comb out, cut or otherwise work on the wig, the wig form ispreferably supported on a fixed post so that the operator need not holdthe wig form in place.

Commercial establishments which deal in wigs generally have fixed posts.However, women in the home and beauty parlors have need for posts thatcan be removed. Removable posts have been known in the art but suchposts have generally been unnecessarily complex in construction, bulkyand complex to operate.

- SUMMARY OF THE INVENTION Generally speaking, in accordance .with theinvention, a post and clamp assembly is provided with a minimal numberof operating elements. The post provides means for supporting a wig formalong the base thereof as well as along its central bore. The clampassembly operating mechanism is located within the post whereby suchmechanism is completely hidden when a wig form is in place on the post.This prevents the snagging of wig hair and also provides for a finishedappearance such that the post and clamp assembly can be used to displaywigs on wig form.

Accordingly, it is an object of this invention to provide an improvedpost and clamp assembly of simplified construction.

Another object of the invention is to provide an improved post and clampassembly which supports a wig form along the base thereof and along itscentral bore.

A further object of this invention is to provide an improved post andclamp assembly wherein the operating elements of the clamp assembly aresubstantially hidden from view when a wig form is on the post.

Still other objects and advantages of the invention will in part beobvious and will in part be apparent from the specification.

The invention accordingly comprises an article of manufacture possessingthe features, properties, and the relation of elements which will beexemplified in the article hereinafter described, and the scope of theinvention will be indicated in the claims.

BRIEF DESCRIPTION OF THE DRAWING For a fuller understanding of theinvention, reference is had to the following description taken inconnection with the accompanying drawing, in which:

FIG. 1 is a perspective view of a post and clamp assembly constructed inaccordance with a preferred embodiment of the instant invention, showingthe post and clamp assembly mounted to the edge of a table and having awig form mounted thereon as indicated in phantom lines;

FIG. 2 is a sectional view, at an enlarged scale, taken along line 2-2of FIG. 1; and

FIG. 3 is a sectional view taken along line 3-3 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT Post and clamp assembly 11 ispreferably formed with a molded plastic one-piece body member 12 havinga hollow sidewall 13, a top 14 and a circular base 15. Sidewall 13 hasthe configuration of a truncated cone and joins circular base 15 at anenlarged lower end 16. An aperture 17 is provided in top wall 14. Thebase 15 is provided with a planar bottom surface 18 in order that thebody member may rest on and engage a flat surface such as table 19,having a table top 20 with an overhanging edge 21..

A knob 22 has a tapered sidewall 23 which terminates, at the topthereof, in a dome shape portion 24. The lowermost end of sidewall 23may be flanged as at 25 with the diameter of the flange following anextension of tapered sidewall 13. Knob 22 has a planar bottom wall 26disposed opposite top wall 14 and a washer 27 may be interposed betweenknob 22 and top wall 14. Washer 27 is preferably formed of a lowfriction material such as Teflon to permit smooth rotation of the knobrelative to the body member, especially after the body member has beenclamped to the top as hereinafter described.

A threaded shaft 28 has its upper end fixed in knob 24. If desired, knob24 may be formed of plastic material and shaft 28 molded in situ in theknob. Shaft 28 extends through aperture 17 into the hollow body member12.

A generally C-shaped bracket 31 is located partially within body member12. A vertical portion 32 extends between a short top portion 33 and along bottom portion 34. Both the top and bottom portions extendsubstantially at right angles with respect to vertical portion 32.

Top portion 33 is provided with a threaded bore 35 which is threadedlymounted on shaft 28 whereby the rotation of the shaft through knob 24while bracket 31 is held against rotation, causes the bracket to moveinwardly or outwardly of body member 12.

Bottom portion 34 has a flat top surface 36 on which is mounted a pad37. Pad 37 is preferably formed of an antislip material which also aidsin preventing the marring of the surface it engages.

To mount the post and clamp assembly on table top 20, knob 22 is rotatedto extend bracket 31 outwardly of body member 12 until the clearancebetween pad 37 and bottom surface 18 is greater than the thickness ofoverhanging edge 21. Bottom surface 18 is then placed in contact withthe top of table top 20 and bottom portion 34 is oriented into aposition below the lower surface of overhanging edge 21. Knob 22 is thenrotated in a reverse direction so as to draw the bracket 31 into thebody member and tightly clamp the post and clamp assembly onto the tabletop.

With the post and clamp assembly mounted on the table top, the exteriorsurface of body member 12 provides a base for the mounting thereon of awig form 41. Wig forms are well known in the art and, as a standardmatter, have a central tapered bore of standard dimension. Thedimensions of the exterior surface of body member 12 are designed toclosely fit with the tapered bore in the wig form whereby the wig formmay be placed on the body member with the lower surface 42 of the wigform in engagement with the top surface of base 15. In such manner, thewig form is securely held in position so that a wig may be placedthereon for styling, combing, cutting, etc. of the wig.

When the wig form is removed from the post and clamp assembly, theassembly can be removed from the table by loosening the gripping actionbetween body member 12 and bracket 31 by rotation of knob 22.

It will thus be seen that the objects set forth above, among those madeapparent from the preceding description, are efficiently attained and,since certain changes may be made in the above article without departingfrom the spirit and scope of the invention, it is intended that allmatter contained in the the invention which, as a-matter of language,might be said to fall therebetween.
